No converter since it was on a race car , but assume they were to OE specs. Great question and will try to find out , as I probably should have asked the fabricator before I posted this --- heh, AARP member , so I am allowed these Senior moments, ha.

Problem is ,Champale , this is on a Boss 302S, not a regular Boss 302, and I did not pay attention if things were modified or cut, so needed to double check and make sure the unit was full stock . Hate scotch ,but definitely a Senior moment before I checked to make sure all the system is intact and not modified, so.....

Super Senior moment , didn't read the whole damn thing -- yours is a kick ass system and if I was paying attention I would not have screwed up your ad/posting. I have a GT 500 axle back system to sell and I posted it, but I forgot to see if it was modified since it was on my Boss 302S. Even if not ,it does have the dual exhaust tips on each side, so limited to what it would go on. Someone should snap yours up , as it is light , sounds killer and will not have fitment issues mine likely will have. Sorry, old age and bifocals caused me to essentially hijack your thread , though unintentional. Folks want less weight and that is what your system will do - the one I have is definitely heavier and that is why we took it off.

Good luck on the sale .....no Scotch on my part, maybe I should start , even though I don't like the stuff, ha?!@
